I haven’t had much opportunity to try Google Reader (Google’s web-based RSS aggregator), but I gave it a spin yesterday, after exporting my Thunderbird news feeds to an OPML file and importing them into Google Reader. At first glance, it appears to be a very well-designed application – with all the Gmail-like Javascript/Ajax UI magic tricks.
You can tag your news feeds, and create feeds out of one or more tags. The next logical step would be to integrate these tags with something like del.icio.us, and be able to subscribe directly to community-tagged feeds. For instance, if I wanted to create a feed for political news from India, I’d subscribe to “India” + “politics”. That’d really be great. I’m now using the power of the community to aggregate feeds from sources that I’d never be able to find on my own.
